fix: update vendor/loop submodule to valid remote commit

rand · claude · rand · commit 2268cb0409d6 · 2026-02-19T12:51:53.000-07:00
The submodule referenced commit 5ded7c7 which no longer exists on
the remote (likely from a rebase/force-push). Updated to 6779cdb
(latest on rand/loop main) to fix CI checkout failures.
